The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cancel ~100
Cancel active runs. delegationId selects one (announced in progress before spawn — the only handle if a run wedges at startup), threadId all on its thread, neither all. Waits for settlement; if a process tree survives the kill deadline, it still returns and the delegate result warns. Status: cancelled, nothing-active, or not-found (no active run with this ID).
| Name | Type | Req | Description |
|---|---|---|---|
| delegationId | string | – | – |
| threadId | string | – | – |
No output schema declared.
No examples provided.
delegate ~307
Delegate a coding task to OpenAI Codex. Never run codex from the shell — use this tool. Check status before trusting result — a run that spawns then fails returns normally. Set spec, workspace and mode, plus resumeThreadId to resume and reviewTarget in review; leave every other field at its default unless the user asks. See the delegate skill.
| Name | Type | Req | Description |
|---|---|---|---|
| fast | boolean | – | Codex Fast mode; higher credit use. |
| mode | string | – | agent implements; plan returns a structured plan; ask answers; review runs native review. |
| model | string | – | Codex model id. doctor deep:true lists every id. |
| reasoningEffort | string | – | Codex reasoning level. doctor deep:true lists each model's levels. |
| resumeThreadId | string | – | Thread to continue. Reuse its workspace. Forbidden with review. |
| reviewTarget | – | – | Required in review; forbidden otherwise: uncommitted, base branch, or commit. |
| spec | string | yes | Brief with goal, scope, fixed decisions quoted exactly, and acceptance criteria; reference files instead of pasting code. |
| timeoutMs | integer | – | Whole-run cap in ms (default 1h). Mid-turn silence is allowed; startup has a separate 60s first-output deadline. |
| webSearch | boolean | – | Codex's built-in web search. |
| workspace | string | yes | Codex's working directory; not confinement. Must already exist — never create one for the call. |
No output schema declared.
No examples provided.
doctor ~49
Diagnose plugin/CLI/login, recursion, and workspace (default: server cwd). deep adds no-quota help and model-catalog checks.
| Name | Type | Req | Description |
|---|---|---|---|
| deep | boolean | – | – |
| workspace | string | – | – |
No output schema declared.
No examples provided.
